Ibn Saud in the context of "Pan-Islamism"

The Sultanate of Nejd (Arabic: سلطنة نجد, Salṭanat Najd) was the third iteration of the Third Saudi State, from 1921 to 1926. It was a monarchy led by the House of Saud, and a legal predecessor of modern-day Saudi Arabia. This version of the Third Saudi State was created when Abdulaziz ibn Saud, Emir of Riyadh, declared himself sultan over Nejd and its dependencies. On the 2nd of December 1922, the Nejd signed an agreement with Kuwait defining their border with each other. The border would be a straight line along the 29th parallel. In December 1925, the Kingdom of Hejaz surrendered to the forces of ibn Saud, who was thereafter proclaimed king of the Hejaz in January 1926 and merged his dominions into the Kingdom of Hejaz and Nejd.

The Banu Qatadah (Arabic: بنو قتادة, romanized: Banū Qatādah, lit. 'Sons of Qatadah'), or the Qatadids (Arabic: القتاديون, romanized: al-Qatādayūn), were a dynasty of Hasanid sharifs that held the Sharifate of Mecca continuously from 1201 until its abolition in 1925. The Qatadids were the last of four dynasties of Hasanid sharifs (preceded by the Jafarids/Musawids, Sulaymanids, and the Hawashim) that all together ruled Mecca since about the mid-10th century. The progenitor of the dynasty was Qatadah ibn Idris, who took possession of the holy city from the Hawashim in 1201. The Emirate remained in the possession of his descendants until 1925 when the last Sharif of Mecca, Ali ibn al-Husayn, surrendered the Kingdom of Hejaz to Ibn Saud, Sultan of Nejd. The House of Bolkiah, which rules Brunei, claims Qatadid descent and Sayyid status from their ancestor Sharif Ali's grandfather Emir Rumaythah.

The Saudi conquest of Hejaz, also known as the Hejaz-Nejd War, was a campaign by Abdulaziz al-Saud of the Saudi Sultanate of Nejd to take over the Hashemite Kingdom of Hejaz in 1924–25, ending with conquest and incorporation of Hejaz into the Saudi domain.

The Third Saudi state is the current Saudi state and heir to the two earlier states: the first and the second, founded by Abdul Aziz bin Abdul Rahman (also known as "Ibn Saud"), who managed to capture the city of Riyadh on January 13, 1902. A long series of conflicts and conquests ultimately led to the establishment of the modern and contemporary Saudi state, the Kingdom of Saudi Arabia.

The House of Saud (Arabic: آل سُعُود, romanized: ʾĀl Suʿūd IPA: [ʔaːl sʊʕuːd]) is the ruling royal family of Saudi Arabia. It is composed of the descendants of Muhammad bin Saud, founder of the Emirate of Diriyah, known as the First Saudi State, (1727–1818), and his brothers, though the ruling faction of the family is primarily led by the descendants of Ibn Saud, the modern founder of Saudi Arabia. It forms a subtribe of the larger prominent ancient Banu Hanifa tribe of Arabia, from which well known 7th century Arabian theologist Maslama ibn Ḥabīb originates. The most influential position of the royal family is the King of Saudi Arabia, an absolute monarch. The family in total is estimated to comprise 15,000 members; however, the majority of power, influence and wealth is possessed by a group of about 2,000 of them. Some estimates of the royal family's wealth measure their net worth at $1.4 trillion. This figure includes the market capitalization of Saudi Aramco, the state oil and gas company, and its vast assets in fossil fuel reserves, making them the wealthiest family in the world and the wealthiest in recorded history.

The House of Saud has had four phases: the Sheikhdom of Diriyah (1446–1744); the Emirate of Diriyah (1727–1818), marked by the expansion of Salafism; the Emirate of Nejd (1824–1891), marked with continuous infighting; and the current state (1902–present), which evolved into the Kingdom of Saudi Arabia in 1932 and now wields considerable influence in the Middle East. The family has had conflicts with the Ottoman Empire, the Sharif of Mecca, the Al Rashid family of Ha'il and their vassal houses in Najd along with numerous Islamist groups both inside and outside Saudi Arabia and Shia minority in Saudi Arabia.

The Kingdom of Hejaz and Nejd (Arabic: مملكة الحجاز ونجد, Mamlakat al-Ḥijāz wa-Najd), initially the Kingdom of Hejaz and Sultanate of Nejd (Arabic: مملكة الحجاز وسلطنة نجد, Mamlakat al-Ḥijāz wa-Salṭanat Najd), was a dual monarchy ruled by Abdulaziz (Ibn Saud) following the Saudi conquest of Hejaz by the Sultanate of Nejd in 1925. It was the fourth iteration of the Third Saudi State.

In 1932, the two kingdoms were unified as the Kingdom of Saudi Arabia.

Al Khobar (Arabic: ٱلْخُبَر, romanized: al-Khobar) is a city and governorate in the Eastern Province of the Kingdom of Saudi Arabia, situated on the coast of the Persian Gulf. With a population of 409,549 in the city core and 658,550 in the governorate, as of 2022, Khobar forms part of the Dammam metropolitan area along with Dammam and Dhahran, making up the residential core of Saudi Arabia's Persian Gulf region.

The city was founded alongside Dammam by the Dawasir, who moved there in 1923 fearing British persecution with the permission of King Abdulaziz Al Saud. Khobar experienced rapid growth during and after the discovery of oil in Saudi Arabia as it served as the port for the oil exports of Saudi Aramco in the company's early days. Traditionally, Khobar has also been a city of shopkeepers and merchants, and today has several shopping malls in and around it.

The walled town of Riyadh was the original core of Riyadh, the modern-day capital of Saudi Arabia, located on the western edge of Wadi al-Batʼha in present-day districts of ad-Dirah and ad-Doho. It emerged from the city-state of Migrin around 1746 when Dahham ibn Dawwas built a wall and a Al Hukm Palace within it, and ruled as the settlement's chieftain until his overthrow by the First Saudi State in 1773. It was later the center of power of the Second Saudi State for most of 19th century following brief Ottoman presence in the Najd. Abdulaziz ibn Saud recaptured the town in 1902 and made it the base for his 30-year long unification wars that led to the establishment of Saudi Arabia in 1932. The town served as the administrative center of the Saudi government before King Abdulaziz ibn Saud moved his workplace and residence to the Murabba Palace in 1944. In 1950, he instructed the dismantling of the fortifications in order to expand the settlement into a metropolis and the walled town eventually ceased to exist. The area covering the perimeters of the erstwhile town was renamed as the Qasr al-Hukm District in 1973 with the aim of preserving its historical and architectural significance.
